Additionally, as we reported last month, all non-Eco models equipped with a turbocharged 1.4-liter Ecotec engine and automatic transmission will see a higher rating of 38 MPG on the highway, compared to the current 36 MPG observed in the 2011 model.

It also is not quite clear yet as to whether or not Chevy plans on charging extra for a more conventional automatic.

All observed fuel economy gains are attributed to a lower axle ratio for the 2012 models. For more, have a look at the presser.
